I use them often. The reason I use them often: the BLI programmable buttons.
I can select a lot of different sources connected to and/or integrated in different Netlink en BeocontrolLink devices on a lot of devices: for example BLC Line In connected BS5e or BG4000 directly to my Shape or Beoplay A6 or BV Harmony.
I can link/join products with the wheel and one button.
I can put devices on standby even if I am in a different room.
The batteries, normally hold about 6 days on a charge.
Only the B&o app has similar abilities, but there is no other remote capable to control the system this way.
So to me extremely viable.
